I got logged in to my account at FileDen.com and when I tried to access my files I got a message telling me that my account is under maintenance to check back and to contact them if it continues to do this.
Now when I click my download links I get the message:  You don't have permission to access /files/2010/2/12/2759461//Chelle_Fairy_Morph.zip on this server.

I guess this is an improvement as yesterday I couldn't even find find them.
